 # HANDOFF — Brief 5 phút cho session tiếp theo
 
-**Last updated:** 2026-05-04 (Session 8 — **Migration 16: 2-stage dept approval + smart reject + lock edit. Đóng bug anh Kiệt báo: NV duyệt được hết phase PE.**)
+**Last updated:** 2026-05-04 (Session 9 — **Chunk E-bis complete: FE 2-stage panel cả 3 module + UserManager bypass toggle + HĐ/Budget 2-stage mirror PE + 6 test + IdentityFixture. 83 test pass.**)
+
+## TL;DR Session 9 (04/05 — Chunk E-bis sau Session 8)
+
+**Output session 9** — đóng tất cả Chunk E-bis defer từ session 8:
+
+- ✅ **FE PE WorkflowPanel** — Section "Tiến trình duyệt 2-cấp phòng ban" group by phase × dept, highlight amber chờ TPB confirm, badge fuchsia bypass (cả fe-admin + fe-user).
+- ✅ **FE UsersPage UserManager** — Column "Bypass" + button ShieldCheck toggle CanBypassReview, badge fuchsia khi enabled. UserDto thêm field.
+- ✅ **HĐ 2-stage logic** — `ContractWorkflowService` thêm UserManager DI + mirror logic từ PE service. `ContractDepartmentApprovalFeatures.cs` List query. Endpoint `GET /contracts/{id}/department-approvals`. FE `WorkflowHistoryPanel` section mới.
+- ✅ **Budget 2-stage logic** — `TransitionBudgetCommandHandler` thêm INotificationService + IDateTime DI + 2-stage. `BudgetDepartmentApprovalFeatures.cs` + endpoint + FE `BudgetWorkflowPanel` section.
+- ✅ **6 test PE 2-stage** — `IdentityFixture` setup full Identity stack (DbContext SQLite + AddIdentityCore + AddRoles<Role>) reusable. 6 scenario: NV_Review_Blocks / TPB_Confirm_Allows / NV_Bypass / Admin_Skip / Reject_Sets / Resume_Jumps_Back.
+- ✅ **Verify**: Build pass + 83 test pass mỗi commit (54 Domain + 29 Infra: 17 codegen + 6 PE WF Application + 6 PE 2-stage).
+- ✅ **5 commit pushed** Gitea (E2 → E6).
+
+## ⚠️ CẢNH BÁO session tiếp (Session 10+)
+
+1. **UAT live ngay** với anh Kiệt + 2-3 user — feature 2-stage đầy đủ cả 3 module + UX.
+2. **Tests Contract + Budget 2-stage skipped** — logic identical PE (cùng pattern, cùng entity shape). Pattern `PeTwoStageApprovalTests` reusable nếu UAT phát hiện regression riêng.
+3. **Bypass toggle audit** — chưa log Changelog khi admin toggle CanBypassReview. Audit qua Identity standard column UpdatedAt only. Có thể cần thêm audit row riêng nếu UAT yêu cầu.
+4. **Notify TPB cùng dept** dùng `UserManager.GetRolesAsync` filter `DeptManager` — verify production có user role DeptManager đúng (data already seeded).
+5. **fe-user KHÔNG có UsersPage** — admin-only function. Bypass toggle chỉ ở fe-admin.
+6. **3 endpoint mới List dept-approvals** PE/HĐ/Budget cùng pattern, reuse policy authz `*Read`.
+7. **Cron audit định kỳ 2026-05-01** vẫn EMPTY (`No scheduled jobs`). Có thể recreate khi user yêu cầu.
